# Arrivals and departures planning for [OpenDreamKit mathematical data workshop](https://opendreamkit.org/2019/08/17/WorkshopOnDataInMathematics/) and [OpenDreamKit's final reports sprint](https://opendreamkit.org/2019/08/26/FinalReportsSprint)

Cernay is 9km from the nearest train station (RER B, Saint-Rémy-les-Chevreuse). There are buses from there, but few, so we will mostly be doing car shuttles. This page is the central point of communication for organising those. Please specify here when you plan to arrive / leave and by which means of transportation. Keep an eye on the page for the planning of shuttles.

Until August 25, the RER B will only go until Orsay-Ville.
Replacement buses cover the final section to Saint-Rémy-les-Chevreuse, with RATP staff in green jackets usually there to inform you and guide you to the replacement bus. More at

For the math data workshop, Samuel will be in charge of the shuttles: [phone].

For the final reports sprint, Nicolas will be in charge of shuttles: [phone].
